Operating System: macOS 10.14 Mojave

Hi there,

 

My HP Z420, which I dual boot with PopOS Linux and a MacOS install, is having boot issues with a 4TB SATA hard drive I’m trying to install. Across two HDD units, I’ve formatted the drives to general success (in ExFat, using a GUID Partition Map), only to have the disks stop working as soon as I reboot, with the Z420 BIOS, on version 3.94, throwing out an A2 disk error. It does not allow me to access the BIOS with the drive installed; the only thing that seems to make the machine work again is if I remove the disk from the SATA line entirely. Additionally, plugging in the drives to a USB-to-SATA adapter does not work.

 

To be clear, I am not running Windows and don’t even have a partition of it on this machine, and this appears to be a BIOS problem as I cannot access the BIOS with the disk installed. Does anyone have any insights as to what I can do to fix this, or is this more broadly an issue with the disks?

Because of your non-Windows OS, I can only offer limited support. (Don't use Linus, and no MAC here).

Update: I ended up returning the 4TB drive and replacing it with a name-brand 2TB drive. One difference is that I formatted the drive FAT32, rather than ExFAT. That seems to be helping, as the drive has been formatted and rebooted without any trouble so far. I’m going to hold off on accept as solution until I’ve had a day or two to mess, but it seems the machine may have been having issues with the ExFAT format on the disk.
